Due to unknown reasons, the PSU of our server burnt out. Luckily we switched it off immediately and therefore the other electronic components are not affected. However, the PSU is beyond repair and needs replacement. We will get one as soon as possible. In the meantime, we hope that you can still enjoy Team Fortress 2 in other servers.
On behalf of the Trilogy.hk admin team, I apologize for the inconvenience caused by this incident.
